Didn't you post the same question yesterday? Perhaps nobody answered because your question is unanswerable. You need to describe what the strings are like and what the patterns are like if you want advice on speeding things up. Duncan Murdoch

Hi there, I have a data frame DF with 40 millions strings and their frequency. I am searching for strings with a given pattern and I am trying to speed up this part of my code. I try many options but so far I am not satisfied. I tried: - grepl and subset are equivalent in term of processing time grepl(paste0("^",pattern),df$Strings) subset(df,

1) What is easy for one person may be very hard for another, so your question is really unanswerable. You do need to know C and Fortran to get through the source code. Get started soon reading the R Internals document if it sounds interesting to you... you are bound to learn something even if you don't stick with it. If you have questions about the internals though, you should read the Posting...

There are less draconian measures that are in my opinion equally secure from a practical standpoint but I am sure that you can figure those out on your own. The transparency issue is really unanswerable. There exists a school of thought that if you are going to administer a Linux system (or OS of the proponent's choice) then you should learn the command syntax of every command that you are called upon to use.

How difficult is it to get a good feel for the internals of R, if you want to learn the general code base, but also the CPU intensive stuff ( much of it in C or Fortran?) and the ways in which the general code and the CPU intensive stuff is connected together? R has a very large audience, but my understanding is that only a small group have a good understanding of the internals (and some of those

Aside from the fact that the original question might well be a class exercise (or homework), the question is unanswerable given the data given by the original poster. One needs to know the dimensions of the reservoir, above and below the current waterline. Are the sides, above and below the waterline smooth? Is the region currently above the waterline that can store water a mirror image of the region below the waterli...

I have Windows XP on my computer. I am trying to access the audio on a file that my client has sent me. The message says: Codec is missig. Speex Voice A109 is not installed on your computer. When I try to install it from the internet, it tells me it cannot be installed. Can you give me any help on installing Speex Voice A109 so I can access the audio? Ann Felkins 308-235-4416 e-mail:

Hi All; We would like to build a call center having 2 E1, but we would like to know which card to select: Sangoma or Digium? And card type to be PCI express or PCI 5.0V or PCI 3.3V ? Any advise or special recommendations for the call center? Regards Bilal

Greetings Please forgive the OT question yet I highly value the experience and wisdom on this list I am wondering if anyone here can address the performance difference between having a processor board with say 256KB L2 *and* 2048KB L3 cache *VERSUS* just having the same processor board with just the L2 cache in a centos server environment... Please figure that all other necessary and related

Dear All, Some of the functions in Linkcomm return an error: unused argument(s) (v = V(x$igraph)) Although I follow the guidance in the manual a number of the functions return this error. The igraph vector is an edgelist. Many thanks for any guidance. Best, Nick

Hello, I previously sent this message which was stripped off due to HTML mail. Sorry! Thanks. Hello All, I am new to the list. I have been learning to use R recently and its been great to see so much help available. However I must admit, I have stumbled upon a problem with correlation matrices and was hoping if someone could help. I have an excel workbook with a sheet per drug. Each sheet
